Tariq has $640 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.

He buys a new bicycle for $291.24.
He buys 4 bicycle reflectors for $19.56 each and a pair of bike gloves for $16.52.
He plans to spend some or all of the money he has left to buy new biking outfits for $50.80 each.

Write and solve an inequality which can be used to determine
x, the number of outfits Tariq can purchase while staying within his budget.
Answer

1 answer

The inequality that can be used to determine the maximum number of outfits Tariq can purchase while staying within his budget is:

640 - 291.24 - (4 * 19.56) - 16.52 - (50.80 * x) ≥ 0

Simplifying the inequality:

640 - 291.24 - 78.24 - 16.52 - 50.80x ≥ 0

254.00 - 50.80x ≥ 0

To solve for x, we isolate the variable:

50.80x ≤ 254.00

x ≤ 254.00 / 50.80

x ≤ 5

Therefore, Tariq can purchase a maximum of 5 biking outfits while staying within his budget.
